What does it mean to rekey a lock?
Rekeying changes the inside of a lock so that a different key operates it. The lock stays on the door. The handle, the deadbolt, the finish and the hardware you already like all stay exactly as they are. What changes is the key that works.
Inside a standard cylinder there is a row of small pins of different lengths. The cuts on your key lift each pin to exactly the right height so the cylinder can turn. When we rekey a lock, we take the cylinder apart and set the pins to a new combination that matches a new key. The old key will still slide into the keyway, but it no longer lifts the pins correctly, so it will not turn. To anyone holding an old copy, that lock is now just a lock they cannot open.
People search for this under a lot of names: rekey locks, lock rekeying, house rekey, home lock rekey, rekey door locks, apartment lock rekey, commercial rekey. The idea is the same in every case. You are controlling who holds a working key without paying for all-new hardware. What differs from job to job is how many cylinders are involved, what brand they are, and whether you want them all on one key or separate keys.
When should you rekey your locks?
The simple test is this: do you know exactly who has a key to your door? If the honest answer is no, rekeying is worth doing. Most calls we get for this service fall into a handful of situations.
- Rekey locks after moving: the previous occupant, their family, a cleaner, a contractor or a real estate contact may all still have keys.
- Rekey locks after buying a house: sellers often hand over the keys they know about, but nobody can vouch for every copy made over the years.
- Rekey locks after a tenant moves out: even a tenant who left on good terms may have given a copy to a friend or relative, and you cannot recover what you cannot see.
- Rekey locks after losing keys: especially if the keys had an address on them, were taken in a bag or a car, or you simply cannot say where they went.
- After a roommate, partner, employee or helper leaves and you would rather not rely on getting every copy back.
- When you want every lock on the property to work with one key instead of a ring of five.

Call (213) 577-1366What about keys you simply misplaced?
We will tell you honestly if you do not need to rekey. If you lost your keys in the house and expect to find them, waiting a day or two is reasonable. If they disappeared somewhere outside, with any link to your address or your car, rekey sooner rather than later. The cost of rekeying is usually modest compared with the worry of a missing key that nobody can account for.
How we rekey your locks, step by step
Here is how a typical residential rekey in Hawaiian Gardens goes, from the first call to the last key test.
- You call (213) 577-1366. We answer around the clock, so a late evening or Sunday call gets the same attention as a weekday one. Tell us how many doors, what kind of locks, and why you are rekeying.
- We talk through the job on the phone: what kind of locks you have, whether there are deadbolts, knob sets, gate locks or a mailbox involved, and what affects the cost for your particular doors.
- A mobile technician comes out in one of our vans with the pinning kits, key blanks and cutting equipment needed to finish the work on site.
- Before touching anything, we look at each lock. We check the brand, the keyway, and the condition of the cylinder and latch, and we confirm that rekeying is the right choice for that lock.
- We remove the cylinders, disassemble them, replace the pins with a new combination and reassemble them. Where you want several doors on one key, we pin them to match.
- We test every new key in every lock, several times, with the door open and with it closed. We also check that the latch and bolt move freely and line up with the strike plate, because a tired door can fail a perfectly good rekey.
- We hand you the new keys, confirm that the old key no longer turns, and explain how to get more copies cut when you need them.
Should you rekey or replace the lock?
Rekeying is a good fit when your hardware is sound and your only concern is who holds a key. It is often the more economical route, and it spares you the hassle of new finishes and fitting.
It is not the right answer every time. A rekey does not make a weak lock strong. If a deadbolt is loose, worn, damaged, rusting from the inside, or is the sort of builder-grade lock you never trusted, rekeying will give you a new key to the same weak lock. In that case, a lock replacement makes more sense, and our page on changing locks walks through the broader options.
Occasionally a cylinder simply cannot be rekeyed because it is damaged, has been tampered with, or is a type that is not built to be re-pinned. We tell you that at the door, before any work starts, and offer a clear alternative. We will not push a bigger job on you when a rekey will do, and we will not rekey a lock that is better off replaced.

Call (213) 577-1366What affects the price of a lock rekey?
We do not publish flat numbers because the work depends on your doors. We would rather explain what moves the cost so you know what you are paying for. These are the main factors.
- How many cylinders need rekeying. A single front door is a smaller job than every door, deadbolt, gate and mailbox on a property.
- The brand and type of lock. Common residential locks are usually straightforward. Restricted or high-security keyways take more care and sometimes special parts.
- The condition of the hardware. A cylinder that sticks, a worn latch or a misaligned door may need repair on top of the rekey.
- How many keys you need cut, and whether you want them keyed alike across several locks.
- The time of day. Overnight and holiday calls involve pulling a technician out of their off hours, and that affects the cost.
- Where the job is and how many stops it involves. Hawaiian Gardens is a good distance from our Westwood base, and travel is part of the picture for a mobile visit.
- Commercial setups, such as multiple doors, shared keying or a master-key arrangement, which take planning as well as pinning.
Tenant turnover: rekeying rentals between residents
Landlords and property managers are among the most regular rekey customers, and for good reason. When a tenant leaves, you want the next resident to be the only person with a working key to their door. Rekeying between tenants is the standard way to do that. It is usually faster and more economical than swapping hardware at every turnover, and it keeps the door looking the same.
In the small duplexes and modest apartment buildings that make up much of Hawaiian Gardens, a turnover rekey often covers more than one lock. There may be a front-door deadbolt, a knob or lever set, a screen-door lock, and sometimes a sliding-door lock as well. We can rekey the set to a single key so a new tenant is not juggling a ring of different keys.
If you manage several units, we can work with you on a consistent approach to turnovers, including keying schedules and keeping track of which key works where. Our page for landlords covers that side of the business in more detail.
Commercial and business lock rekey
Rekeying is not just for houses. Shops, offices and small businesses face the same questions: a former employee, a departed manager, a vendor who once had access, or a set of keys that went missing. A commercial rekey changes who can open your doors without a full hardware changeout.
Business jobs tend to be a little more involved. There may be a front door, a back door, a storeroom, an office and perhaps a rear gate, and different people may need access to different doors. We can pin everything to one key, or set it up so some keys open some doors and not others. If your building has grown past what a ring of separate keys can manage, a master key system may be the better long-term answer, and we can walk you through that.
Rekeying is only part of what a business needs from a locksmith. If you are also dealing with worn exit hardware, storefront doors or access control, our commercial locksmith page covers that work. For this page, the focus stays on changing the keys.

Call (213) 577-1366Lock rekey in Hawaiian Gardens: what our work looks like here
Hawaiian Gardens covers roughly one square mile, which makes it one of the smallest and densest cities in Los Angeles County. Most of what we see under ZIP code 90716 is small post-war single-family homes, duplexes and modest apartment complexes, with much of the housing stock dating from the 1940s through the 1960s. That shapes what a rekey looks like here.
In the post-war homes near the Fedde Sports Complex and the Elaine Avenue area, a residential rekey is a regular request. These homes have usually changed hands more than once, and a buyer or new renter often wants every lock on a single new key. Many also have security screen doors, so we check that the screen-door lock works with the new key setup instead of leaving you with one more key to carry.
Along the Norwalk Boulevard corridor, many apartment complexes use shared pedestrian gates and banked mailboxes. A unit rekey changes the door, but the gate and mailbox can still carry older keys, so when a tenant moves out it is worth asking whether those need attention too. If someone is locked out of an apartment while sorting this out, our apartment lockout page covers that situation, and a lost or compromised mailbox key is handled under mailbox lock replacement.
Along the Carson Street corridor, the business side comes in. Small businesses near The Gardens Casino sometimes need doors rekeyed after a change in staff or ownership. Around the Pioneer Park and Civic Center area, we see a mix of homes and small properties where the same questions come up: who has keys, and how many do we need?
The local climate is kind to locks. The city sits on the flat coastal plain several miles inland. Marine-layer mornings bring some dampness, but salt-air corrosion is modest compared with beach cities, and summer heat is moderate, so wood doors move only slightly with the seasons. That generally means cylinders in this area are not eaten away by the environment. We still check each lock, because age and heavy use wear them down regardless of weather, and a 1950s door may have had its hardware swapped several times over the decades.
Why call Wilshire Lock & Key for a rekey
We have been in business since 1987, serving 140 cities across Los Angeles and Ventura counties. Our storefront is at 10740 Wilshire Blvd in Westwood, and our mobile vans bring the work to you. When you call, you reach us, not a call center that hands your job to whichever subcontractor picks up. We are one company, with no dispatch middlemen between your call and the person at your door.
David, the owner and lead technician, oversees the work. That matters for rekeying, because the job looks simple but depends on detail: the right pins, careful testing and an honest opinion about whether a lock is worth keeping.
Our line, (213) 577-1366, is answered 24 hours a day, seven days a week, all year. If you need to speak to us about an after-hours move-in, a tenant who left in the night or a set of keys you lost on the weekend, you can call at any time.
One practical point worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start work. That is a fair question to put to anyone who comes to your door, and it is a good habit generally.
Frequently asked questions
Will my old keys still work after a rekey?
No. After a rekey, the old key can still go into the lock, but it will not turn. The pins inside have been changed to match a new key, so any copy of the old one, wherever it is, stops working on those locks.
Do I need to be home while you rekey the locks?
Someone should be there to let us in and take the new keys, but you do not need to hover over the work. For a vacant rental or a house you have just bought, we can arrange access in other ways, which we can work out on the phone.
Can you rekey all the locks in my house to one key?
In most cases, yes. If your locks are standard cylinders, we can pin each of them to the same key, so one key opens the front door, back door and deadbolts. If a lock has an unusual keyway or is a different brand, we check on site and tell you what is possible.
Is rekeying as secure as installing new locks?
It depends on the lock. Rekeying protects you from old keys, but the lock is still the same lock. A solid deadbolt that has been rekeyed is a sound choice. A worn or low-grade lock is still worn or low-grade after rekeying, and we will tell you if replacing it would serve you better.
Can you rekey a lock if I have no key at all?
Yes, as long as the lock itself is in working order. If you are locked out, we have to get the door open first, then rekey the lock so you have a fresh set of keys. We will explain the sequence on the phone.
How do I get extra copies made after a rekey?
We can cut extra keys for the new setup when we rekey, or you can come back later. Our key duplication page explains how that works. A good tip is to cut copies from the new key rather than from an old one.
Can smart locks or electronic locks be rekeyed?
Many smart locks still have a standard mechanical key cylinder as a backup, and that cylinder can sometimes be rekeyed. The electronic side, like codes and app access, is separate, and we confirm what is possible in person since it varies by model.
Do you come out to Hawaiian Gardens at night or on weekends?
Yes. Our phone line at (213) 577-1366 is answered 24 hours a day, every day of the year, and our mobile vans serve Hawaiian Gardens. Call whenever the need comes up and we will go through the options with you.
